Frequently Asked Questions - ACD-45PQ Amprobe
How do I measure AC current with the Amprobe ACD-45PQ?
Set the rotary switch to the AC current range (A~). Clamp the jaw around a single conductor. Read the value on the LCD. Ensure the conductor is centered for accuracy.
What is the maximum voltage the ACD-45PQ can measure?
The maximum DC voltage is 1000V, and the maximum AC voltage is 750V. Do not exceed these limits.
How do I replace the battery in the ACD-45PQ?
Turn off the meter and disconnect test leads. Remove the battery compartment screw on the back. Replace the 9V battery. Reattach the cover and screw.
What does the 'HOLD' button do?
The HOLD button freezes the current reading on the display. Press it again to release the hold.
Can I measure DC current with the clamp?
No, the ACD-45PQ measures only AC current via the clamp. For DC current, you would need a different model.
How do I test continuity?
Set the rotary switch to the continuity function (often marked with a diode/Ω symbol). Connect test leads across the circuit. A beep indicates continuity (<30Ω).
What is the accuracy of the ACD-45PQ?
Accuracy varies by function. For example, AC voltage is ±(1.5% + 5 digits). Refer to the manual for full specifications.
The display shows 'OL', what does it mean?
OL stands for Overload. It indicates the measured value exceeds the selected range. Switch to a higher range or reduce the input.
How do I clean the meter?
Use a damp cloth with mild soap. Do not use solvents or immerse the meter. Dry thoroughly before use.
What is the auto power-off time?
The meter automatically powers off after 30 minutes of inactivity to save battery.
